Copper-Catalyzed Rearrangement of (Z)-Propynal Hydrazones via N−N Bond Cleavage
TLDR
Propynal hydrazones are successfully converted to the corresponding 3-aminoacrylonitriles in the presence of copper catalysts in good to high yields through C-N bond formation and subsequent β-elimination involving cleavage of N-N and C-H bonds.About:

Copper-Catalyzed Rearrangement of (Z)-Propynal Hydrazones via N—N Bond Cleavage.
TL;DR: In this paper, a variety of β-aminoacrylonitriles is prepared in the reaction, catalyzed by Cu(OAc)2, followed by the Z/E-isomerization, induced by AcOH.

Gold-catalyzed cycloisomerizations of enynes: a mechanistic perspective.
TL;DR: The proposed involvement of cyclopropyl metal carbenes of type 4 in the electrophilic activation of enynes by transition metals was first substantiated in reactions catalyzed by Pd(II), in which the initially formed cycloprostyl palladiumCarbenes undergo [4 + 2] cycloaddition with the double bond of the conjugate enyne.
